Before you can do a build, you must run midl to generate the RPC .C
files from the pgpkeysvc.idl.

CLIENT:
  midl -ms_ext -server none  -cpp_opt "-nologo -E" pgpkeysvc.idl

SERVER:
  midl -ms_ext -client none -cpp_opt "-nologo -E -DSERVER" pgpkeysvc.idl

  Latest theory is that this can be used for both:
    midl -ms_ext pgpkeysvc.idl
